The work presented in this report is a proposal for a physical rehabilitation n of the Nyabarongo Upstream Watershed. This is a technical component which is part of an integrated catchment management plan but focuses more on land restoration and rehabilitation. The presented rehabilitation plan should be taken as a guiding plan that will serve as a planning tool at district level and as an IWRM awareness tool, among others, for all concerned stakeholders.
Heavy rainfall in the volcanoes area often results in floods. Whereas the observed floods may appear similar in nature, the dynamics of floods in the volcanoes area are quite different according to their locations: classic torrential rivers in the Musanze urban area and Sebeya catchment, flooded endorheic areas (catchments without external outlet) in Byangabo sector, and flooded “dry thalwegs” north east of Rubavu disctrict. A study was implemented by “Water for Growth Rwanda”. This memo provides the final results. The main studied rivers are the following ones :
Musanze-city sector: Rivers Rwebeya, Muhe and Susa
Byangabo plateau sector: Rivers Murufurwe, Mutobo, Kinoni, Bikwi, Rungu and Nyabitondore.
Sebeya Catchment: Rivers Sebeya, Karambo and Pfunda
